If you’ve ever shopped for a Princess Alaska cruisetour, you’ve probably stared at a code like T6AFB4 and wondered what on earth it means. The good news: there’s logic to the chaos. Here’s the decoder.

The basic structure

Princess cruisetour codes follow a pattern: [Tour Type] [Length] [Direction Variant] [Year Suffix].

For T6AFB4:

  • T — Cruisetour (combination of land + sea)
  • 6 — Internal product code for Princess’s “Denali Explorer” itinerary
  • AFB — Specific lodge sequence + direction code
  • 4 — Cabin tier or version

Different code prefixes:

  • T-codes — Cruisetours (land + sea)
  • N-codes — Cruise-only northbound voyages
  • S-codes — Cruise-only southbound voyages

What’s the Denali Explorer specifically?

The T6AFB4 itinerary is what Princess calls the “Denali Explorer 11-Night Cruisetour.” It combines:

4 nights LAND in Alaska’s interior:

  • Hotel Captain Cook (1 night, Anchorage)
  • Mt. McKinley Princess Wilderness Lodge (1 night)
  • Denali Princess Wilderness Lodge (2 nights)

7 nights CRUISE on Princess’s Voyage of the Glaciers route:

  • Whittier (embark)
  • College Fjord scenic cruising
  • Hubbard Glacier scenic cruising
  • Glacier Bay National Park scenic cruising
  • Skagway, Juneau, Ketchikan
  • Inside Passage scenic cruising
  • Vancouver (disembark)

That’s two completely different Alaska experiences in one package — interior wilderness + coastal glaciers — bookended by a famous rail journey from Denali to Whittier.

Why this specific itinerary?

Most Alaska first-timers want both sides of the state. They want to see Denali (the interior, the mountain, the wildlife). And they want the glaciers (Inside Passage, Glacier Bay, Hubbard).

Doing them as separate trips means flying in and out twice and missing the connection. The Denali Explorer connects them via Princess’s exclusive Direct-to-the-Wilderness rail line — a one-way train through the Alaska Range that’s a destination in itself.

What’s included vs not included

Included in T6AFB4:

  • All hotel/lodge accommodations
  • All cruise meals and entertainment
  • Scenic railway from Denali to Whittier
  • All ground transportation
  • Denali National Park Natural History Tour

Not included (book separately):

  • International flights to Anchorage and from Vancouver
  • Optional shore excursions in cruise ports
  • Optional flightseeing or dog-sledding add-ons in Denali
  • Travel insurance, gratuities
  • Specialty restaurant fees onboard, drinks packages

Why book through EWT Tours instead of directly with Princess?

Three reasons:

  1. Small group: We cap our group at 16 travelers within the larger ship — you get the EWT Tours treatment with Daniel as your host on land and sea
  2. Pre-arranged group dinners at restaurants Princess passengers don’t access individually
  3. Curated shore excursions — we vet each port’s options and book the right one for our group

The cruisetour itself is Princess’s product. The EWT Tours layer is the guide, the small group, the social experience, and the local knowledge.
